In case you missed the big news, the Fuller House star revealed to Peoplethis morning that he was expecting his first child with fiancée Caitlin McHugh.

"My life has been 'over blessed' but this could be my happiest moment ever!" he shared on Instagram when celebrating the news.

And while he may have played a fantastic father on TV, John realizes that his life at 54 is about to change in more ways than one. As we celebrate the beloved Hollywood actor on his exciting family news, we're reminded that John certainly isn't the first star to become a dad after 50.

Take a look at a few more Hollywood studs who became a father later on in life in our gallery below.

Hugh Grant

The Love Actually star was about 51 when he became a dad to daughter Tabitha with Tinglan Hong after—as his rep called it—a "fleeting affair." Fatherhood agreed with the British actor, because he had three more children in quick succession—son John, with TV producer Anna Eberstein, and son Felix, with Hong, arrived within months of each other; and another daughter with Eberstein.

"Everyone was right all these years, saying, 'Hugh, why don't you have some children? It changes your life," Grant said on Ellen in 2012, when Tabitha was 6 months old. "Now that I have one, it is life changing. I recommend it. Get some!"

Admittedly, he added, Tabitha—whose name in Chinese, Jīng Xǐ, means "Happy Surprise—was "a little bit of a surprise. But it's a very nice surprise."

Bryan Adams

After his parents divorced, the "Summer of '69" rocker was estranged from his dad for 12 years. Adams sought him out in 1992, a reunion he described 10 years later to The Guardianas "nothing but embraces and tears." Asked if experiencing what it was like to grow up in a broken home was a reason he hadn't had his own family yet, he said, "Well, that's a very deep question. I don't know if I can answer that, I don't know."

Down the road a bit, the singer-activist-photographer was 51 when he welcomed his first child, a daughter named Mirabella Bunny, with Alicia Grimaldi in 2011; another daughter followed in 2013. But he still didn't want to talk much about his private life, telling the Telegraph in 2015, "It's nobody's f--king business but my own."

Simon Cowell

The longtime bachelor and harshest critic on two continents, a man who had made children cry on TV, turned into one of the most doting celeb dads around in 2014, when son Eric was born on Valentine's Day. The America's Got Talent judge and record impresario was 54.

"I'm not brilliant with babies," Cowell admitted to Paradewhen girlfriend Lauren Silverman was still pregnant. "I never know what to do. But [once he's older] I think I'll be a good dad in terms of advice. And then I'll get to do all the things I want to do, like go to Disneyland or Universal Studios, teach him how to drive—I love all that."

A few weeks after Eric was born, he told Extra, "I was born to be a dad..."I actually said to Lauren beforehand, 'What if I like the dogs more than him?' and she said, 'You're gonna be absolutely fine,' and then literally within seconds of him being born, I got it!"

Jeff Goldblum

"I never really particularly passionately wanted children," the idiosyncratic actor, single at the time, shrugged to London's Independent in April 2008.

Six years later, not long before marrying third wife Emilie Livingston, he told GQ.com he did not have babies on the brain. "But, you know, they are cute, aren't they?" he added, presumably with utmost Goldbluminess.

Less than a year later, on July 4, 2015, the couple welcomed son Charlie Ocean. Goldblum was 62. Another boy, River Joe, arrived on April 7, 2017.

He told Parade in July 2016 that he simply "never seriously considered [having children] until Emilie. I'm at a different place now. I was enthusiastic to marry her and try to have a baby." To USA Today he admitted that he had to "wrap my head around" the idea of becoming a dad. But ultimately "things have shifted. I think there's a perspective, maybe, about acting and, you know, career things that gets shifted with home life being so full and nutritious, and nourishing and wholesome. It's really fun."

Steve Martin

The Father of the Bride star and full-on renaissance man was 67 when he and his second wife, Anne Springfield, welcomed daughter [insert name here]. (The couple have yet to publicly reveal her name, one of the celebrity world's greatest gifts being privileged anonymity.)

In his first appearance on The Late Show With David Letterman after becoming a dad, Martin plunked a baby monitor on Dave's desk. "The baby's back at the hotel and I'm a responsible dad," he deadpanned.

"Oh, it's fantastic—you have all the time in the world," Martin further quipped to Australia's Daily Telegraphin 2016 about being an older father. "You're all set and secure in life, and you're not building your career, so you have a lot of time."

But though he's only broadened his creative horizons in recent years, he insisted he really does have more time. "When I was younger, I was selfish and focused on my career. Now I'm just hanging around the house playing with her. It's great."

Chris Noth

The Sex and the City star was 53 when he and Tara Lynn Wilson welcomed son Orion in 2008—and he would go on to say that he simply wasn't ready beforehand (and having not met the right woman yet was part of it).

"I think a child changes the equation in your life," Noth told AskMen.com in 2014. "We value freedom a lot in society now. We live longer. The idea of being in your 30s settling down and having a family, I just think people realize they don't have to do that right away. There's still time."

He added, "Also, I had some pretty big relationships in my life. I'm glad I didn't get married. I've been in love maybe four times before that. If I had gotten married, I'd be paying four different alimonies."

Elton John

The iconic singer-songwriter was 63 when he and now-husband David Furnish (48 at the time) welcomed their first son, Zachary, via surrogate on Christmas Day in 2010. Lady Gaga is one of his godmothers, not too shabby.

About a month after Zachary was born, John told Pop Sugar about his decision to have children: "I've had an incredible life. I experienced great joys and great sadness, great highs, great lows, I pulled myself together, I got sober, I got my self respect back, and I tried to make up for lost time by doing good things for other people. But the only thing missing from my life that I hadn't experienced was having a child. And, David and I thought about this and decided to have one and so I think as much as I can teach my child many great things, he's gonna teach me 1,000 times more about myself—what I need to do, how I need to look at things. I've never lived that life before."

Their second son, Elijah, was born in 2013, after which the doting dads said their family had been completed "in a most precious and perfect way."

As for John's future parenting style, one close friend and co-star has an idea of what could be coming soon.

"He is going to be a great father. I mean, look at me, I turned out great," Fuller House star Blake Tuomy-Wilhoit shared with E! News. Well played, young man.
